To aZZ whom it may concern.-

Be 1t known that I, HANS AMUNDSON, of

. Racine, in the county of Racine, and in the State of Visconsin, have invented certain new and usefnlImprovements in Seed-Servers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to seed-sewers; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described With reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a plan view of a seeder constructed according to my invention; Fig. 2, a vertical transverse section of the same; Figs. 3, 4, and 5, detail views of the clutch mechanism; Fig. 6, a longitudinal vertical section of my seeder; Fig. 7, a detail View of the clutch-lever; Fig. S, a plan view of the feed-box; Fig. 9, a section taken on line 9 9, Fig. S; Fig. l0, a plan view of the distributer; Fig. l1, a detail view of the clutch, and Fig. l2 a similar View of a bracket einployed in my machine. Figs. 13 and 14 are sectional views of another form of clutch.

Referring by letter to the drawings, A rcpresents the rightangular frame or support, that is designed for attachment to the rear of an ordinary farm-Wagon. Secured to the vertical portion of the frame A is a bracket, B, provided with bearings ci a for a horizontal shaft, C. By the employment of a single bracket I am enabled to cheapen the cost of the machine by lessening the number of pieces that constitute the same, and also insure the bearings a a for the shaft C being in line with each other. Keyed to the outer end ofthe shaft Gis ahub, D, provided with clutch-teeth b, that engage similar teeth, c, on the loose hub d of a shell, E. The inner face of the shell is provided with lugs e, that are bored ont and tapped to receive set-screws h, that pass through segmental slots f in a sprocket-wheel, F, and serve to hold said shell and the sprocketwheel together, as best shown in Fig. 2. Arranged within the shell E, between the lugs e thereon and lugs g on the sprocket-wheel F, are spiral springs i, and secured to the hub of said wheel is a horizontal spannenarin, G, that operates in a guide formed by two lugs,j j, on the bracket-B, and is connected to a vertical crankarni, G that has ils bearings in said bracket and another bracket, B. The bracket B' is provided with scrrations lr, that engage with a dog, H', pivot-ed to a hand-lever, H, that is secured to the upper end of the crank-arm G', and a spring,`m,A is arranged between said lever and dog to automatically hold the latter in operative position.

Keyed to the shaft C is a pinion, l', that meshes with another pinion, I, on a vertical shaft, J, that is stepped in the bracket B at a. and hns loosely arranged thereon a distributer, K, the latter having` its hub provided with teeth a, that mesh with a gcarwvheel, L, on the first-named shaft.

The horizontal portion of the support A is cutaway to receive a circular feed-box, M, and this box is provided with an arm, M',

that has pivoted thereto a weighted dog, N,

the latter being designed to engage a rack, N', on said support. By operating the arm M' of the feed-box M the delivery-spouts p of said box are brought more or less on either side of the center ofthe distribnter to vary the throw of the seed, and it will be noticed that I provide the distributor-wings at their outer ends with ri ght-angle iianges q, the latter serving to retard said seed, and thereby prevent it from being th rown too far.

Centrally arranged in the feed-box M is a circular flange, I), that forms with the base of said box a cup to receive the seed from the hopper Q, that is bolted to a suitable baseboard,Q. About one hall' of the dange P is of less height than the other, and is provided with a series of seed openings, o'.

Held on the distribnter-shaft .I by means of a pin, s, is a slotted sleeve, It, and depending from this sleeve are a series of right-angular arms, R', each of the latter carrying a cut-off block, S, for the seed-passages r in the dange P. Each of 'the cnt-ofi' blocks S is fitted between t\vo radial flanges, T, on an annulus, T, and this annulus extends down into the feedboX M. said flanges being strengthened by a ring, T2, integral therewith or connected thereto.

Pivotally connected to the sleeve R just IOO through a slotted plate, V, on the support A, and this plate may be provided with ascale or index.

By a movement of the` lever U the cut-Off blocks S are raised or lowered to vary or entirely close the seed-openings r in the flange P. The seed, escaping through the openings 1' in the flange P,is forced along by the radial flanges T on the annulus T to the deliveryspouts p of the box M and drops onthe distributer to be broadcasted.

The sprocket-wheel F is intended to be connected by a drive-chain to a similar wheel that is usually secured on the rear wheel of the vehicle to which my seeder may be attached, and said seeder is thrown in or out of operation by a movement of the lever II. When this lever H is operated to cause an engagement of the clutch-teeth on the hub D and shell E, the machine will not start until the springs z' have been compressed, and thus I avoid any strain or jerk during said operation.

rlhe distributer being loose on its shaft and connected by a small pinion with alarge gear- Wheel, its rotation is very rapid as compared with that 0f the feed mechanism driven by said shaft, the latter being geared, as above described, to the shaft that is driven by the sprocket-gear.

In Figs. 13 and 14 I have shown another form of clutch, that consists of a sleeve, C, on the shaft C, this sleeve being provided with an annular plate, C?, the latter having recesses f in its periphery to serve as guides for pins or bolts h, that unite the shelLE and sprocketwheel F, as best illustrated by Fig. 14. The shell E in this form of clutch has a lug, g, between which and a lug, g', on the plate C2 is arranged a spiral spring, z', and to said plate and one of the pins or bolts 7L are connected the respective ends of a coil-spring, i', as best illustrated in Fig. 13. Instead of the spiral spring in this form of clutch, I may use another coil-spring, the latter being fastened to the shell and plate on the sleeve in a manner similar to that described for the one already employed. The latter form of clutch is for the same purpose and has the same action as the one previously described, the main difference being that instead of two spiral springs I employ one 0r two coil-springs, and in both forms the resistance of the springs is against the rotation of the drive-shaft.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is- Y l. In a seed-so wer, the combination, with the main drive-shaft and distributer-shaft, of a single bracket provided with a step for said distributer-shaft and having each of its ends in the form of a bearing for said main shaft, substantially as set forth.

2. In a seed-sower, a distributer having the outer ends of its wings provided With rightangle flanges, substantially as set forth.

3. In a seed-sower, the combination of a distributer, a seed-box having delivery-openings and a central circular ange having one side thereof provided with vertical seed-passages, a series of vertical cut-offs for the seed-passages, an annulus provided with a series of radial flanges and arranged adjacent to the cut-offs, and suitable mechanism for rotating the distributer and annulus, substantially as set forth.

4. In a seed-sewer, the combination of a drive-shaft, a hub keyed thereto and provided with clutch-teeth, a shell loose on the shaft and interiorly provided with lugs e, a sprocket- Wheel secured to the shell and having lugs g that enter the same, springs arranged between the lugs on saidshell and those on thesprocketwheel, and suitable means for actuating the loose section of the clutch mechanism, substantially as set forth.

k5. In a seed-sewer, the combination of the feed-box M, provided with the arm M', ange P, and spouts p, the pivoted dog N, rack N, distributer K, shaft J, sleeve R, having depending arms It, cut-offs S, annulus T, provided with the radial flanges T', the lever U, and suitable means for driving said distributer and shaft, substantially as set forth.

6. In a seed-sower, the combination of the shaft C, hub D, provided with clutch-teeth b, the shell E, having lugs e, sprocket-wheel F, having the slots fand lugs g, the spiral springs 1J, Spanner-arm G, crank-shaft G', hand-lever H, spring-dog Il', and serrated bracket B', substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Racine, in the county of Racine and State of Wisconsin, in the presence of two witnesses.
